Integrated database system and computer-readable recording medium recorded with program for managing database structure thereof

1. An integrated database system, comprising: a storage device containing database information thereupon, said storage device containing a plurality of records, wherein a single record of said plurality of records comprises a record part of a relational database and a record part of a non-relational database therein, wherein the record part of the non-relational database comprises at least a parent record part, said system further comprising a processing device connected to said storage device for performing relational operations and data manipulation on the plurality of records, wherein said processing device is configured to process a relational operation and a data manipulation with a single command, wherein said processing device performs a relational operation on the record part of the relational database to extract a predetermined set of records, and wherein said processing device performs data manipulation on the predetermined set of records.

2. An integrated database system as recited in claim 1, wherein said record part of said single record comprises the parent record part and at least one child record part linked to the parent record part.

3. An integrated database system, comprising: storage means containing database information thereupon, said storage means containing a plurality of records, wherein a single record of said plurality of records comprises a record part of a relational database and a record part of a non-relational database therein, wherein the record part of the non-relational database comprises at least a parent record part, said system further comprising processing means connected to said storage means for performing relational operations and data manipulation on the plurality of records, wherein said processing means is configured to process a relational operation and a data manipulation with a single command, wherein said processing means performs a relational operation on the record part of the relational database to extract a predetermined set of records, and wherein said processing means performs data manipulation on the predetermined set of records.

4. An integrated database system as recited in claim 3, wherein said record part of said single record comprises a parent record part and at least one child record part linked to the parent record part.

5. A computer-readable medium containing a computer program thereupon, said computer program configured to: perform a relational operation and a data manipulation on records of a database structure, wherein said records comprise a record part of a relational database and a record part of a non-relational database, wherein the record part of the non-relational database comprises at least a parent record part, wherein said program is configured to process a relational operation and a data manipulation with a single command, wherein said program performs a relational operation on the record part of the relational database to extract a predetermined set of records, and wherein the program performs data manipulation on the predetermined set of records.

6. A computer-readable medium according to claim 5, wherein said record part of said non-relational database comprises the parent record part and at least one child record part linked to the parent record part.

7. A method of manipulating an integrated database system, said method comprising the steps of: performing a relational operation and a data manipulation on records of a database structure, wherein a record of said records comprises a record part of a relational database and a record part of a non-relational database, and wherein the record part of the non-relational database includes at least a parent record part, wherein a single command processes the relational operation with the record part of the relational database as an object of operation to extract a predetermined set of records, and wherein the single command processes the data manipulation on the predetermined set of records.

8. A method as recited in claim 7, wherein said record part of the non-relational database includes the parent record part and at least one child record part linked to the parent record part.
